SPECIFICATION forming part of Letters Patent No. 754,335, dated March 8, 1904. Applioation led April 2, 1902. Serial No. 101,102. (No model.) Y

To aJZ whom it may concern:

Be it known that I, WILLIAM L. MCCABE, a

citizen of the United States,residing at Seattle,

in the county of King and State of Washing-,-

ton, have invented certain new and useful Im? provements in Portable Conveyers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in portable conveyers, and more particularly to L represents an end elevation of the same. Figs'. A

means for longitudinally cupping the conveyer-belt for preventing lateral displacement lcentrally-arranged supporting-pulleys there-l on,pivotallysupported pulleys extending outside said central pulleys, means being provided for adjustment of said pulleys to varying angles relative to each other.

It also consists of vcertain other novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed. l

In the accompanying drawings, Figure 1 represents a transverse vertical section taken through one set of pulleys and the frame of a portable conveyer embodying .the features of one form of the present invention.v Fig. 2 represents a top plan view of a portion of the conveyer including one set of pulleys. Fig. 3 represents a view in end` elevation of the same. Fig. 4 represents a detail section taken on the plane of line44 of Fig-1. Fig. 5 represents a view similar to Fig. 1 of a slightlymodied construction. Figs. 6 and7 represent views similar'to Figs.- 2 `and 3, respec tively, of the structure shown in Fig. 5. Fig.

8 represents a section through one of the aux-A iliary frame-adjusting mechanisms. Fig. 9

410, 11, and 12 represent similar views to Figs. 1,2, and 3, respectively, ofa modified structure. 5 o

Figs. 13, 14, and 15 represent similar views; respectively, of another modification.,l

Fig. 16S-represents enlarged detail views of the hinge connections betweenthe longitudinally-connecting shafts and the auxiliary frame.- Figs.l 17, 18, and 19 represent similar views to Figs.A 1, 2,-and 3, respectively, of

drawings, which illustrate one embodiment of my invention, 1 l indicate longitudinally-arranged beams, preferably angle-irons, having suitable connecting-bars, as 2, the Whole forming part of a mainframe of the present con-l veyer. Extending parallel with each other and with beams 1 are beams, as 3 3, which, to-v gether with transverse connecting-bars or angle-irons 4:, arranged at suitable intervals along the same, form an auxiliary frame, said auxiliary frame being mounted at each end or at any other suitable points upon blocks, as 5 5,

having beveled under faces 6 6, each provided with a tongue, as 7, slidably engaging a groove, as 8, of its respective supportlng-l block, as 9, each of said supporting-blocks having correspondingly-beveled upper faces,

in which the grooves 8 are formed. Each of blocks 9 is slidably mounted upon a suitable plate, as'lO, extending transversely of the main frame and preferably secured thereto in any suitable manner. A bolt, as 11, isthreadeach other or to separate, whereby, owing to its beveled-faced contact with blocks 5,the auxiliary frame maybe moved'vertically.

At suitable intervals in the length of 4beams 8, -ed into both of blocks 9,;the thread of one 3 are secured flanged collars, as 12 12, whichV y areformed, preferably, with somewhat ovalshaped apertures, in whichare secured cujs, as 13 13, of the same shape in cross-section. The cuIs 13 are arranged in pairs on .the auxiliary frame, and each pair is connected by a shaft, `as 14, each of said shafts carrying a IOO central belt-supporting pulley, as 15. Extending into the open end of each cuii'r13 is a shaft, as 16, bent at its inner end, as atA 17, and pivotally attached at its outer end, as at 17', to a brackea'as 18, each bracket 18 being secured by clamps, as 19 19, or in any preferred manner to the beams 1. Each shaft 16 preferably carries a belt-supporting pulley, as 20.

It will nowbe clear that when the auxiliary frame is at its highest vertical position all of the belt-supporting pulleys will be in horizontal alinement; but when the blocks 9 are drawn toward each other the pulley will move downwardly with the auxiliary frame, the shafts 16 swinging on their pivots .17', they being permitted to move longitudially at their bent ends by reason of their loose engagement with cuffs 13. As the pulley 15 moves downwardly the pulleys 2O are caused to assume increasing angles relative thereto and are supported in downwardly-converging diagonal planes, whereby the carrying-belt will be. lower at its center than at its edges, thereby having a longitudinal cupped condition designed to prevent lateral displacement of the l articles conveyed.

the cuifs 13 are omitted and shaft 14 is sup-- described when the It will be obvious that in addition tothe function or the holt 11 of positioning the pul-v leys 20 in diagonal planes it also retains or locks said pulleys in such position until it is further operated.

The operation of the device shown in Figs. 5, 6, and 7 is precisely the same as that above described; but the structure differs in that ported in brackets 13", secured to the longitudinal beams 3 of the auxiliary frame. Laterally-projectingpulley-carrying shafts, as 16, are hingedly connected to `brackets` 13 and are pivotally supported by arms, as 12, which arms are in turn pivoted to brackets 18", secured to the main frame 1 of the device. The triple pivotal support of shaftsl 16 effect an adjustment precisely similar to that above auxiliary frame is moved vertically. f

In the structure shownV in Figs. 10, 11, and 12 the auxiliary frame is preferably held rigid and carries brackets, as 13 carrying shaft 14",

g designed to support a central belt-supporting pulley. To each bracket 13 is pivoted an arm, as 12", carrying a laterally-extending shaft, as' l16", each designed to be provided with a belt-supporting pulley. Each arm 12b is provided with a suitable eye, through which is passed a longitudinal connecting-shaft, as 18 whereby all of the arms 12b of one side of the conveyer are connected,and movement of one will move the others. Now in order to position shafts 161 in diagonal planes it is only necessary to grasp one of arms 12b on each side of the conveyer, swing the same outwardly to the desired extent, and place a block between each of said arms and its reas 1 8d, attached to the main frame.

spective bracket 13", as indicated in dotted lines in Fig. 10. i

The operation of the device disclosed in Figs. 13, 14, 15, and 16 is exactly similar to that last above described, the structure. differing only in that longitudinally-connecting shafts, as 18, are employed which are hinged directly to the auxiliary frame, the central pulleys being arranged as above described, but the lateral pulleys being carried upon shafts, as 16e, secured to brackets, as 12C, which in turn are clamped or otherwise suitably secured to shafts 18C. In this particular em bodiment of the present inventionit is my design to arrange the shafts 16c intermediate the central pulleys, as will clearly appear by reference to Fig. 111; but it will of course beA understood that said shafts 16c may be arranged at any desired points along shafts 18, as may be preferred, without departing in the least from the scope of the invention.

The embodiment disclosed in Figs. 17, 18, 19, and 20 employs a tiXedly-supported auxiliary frame, with central pulleys, as 15d, similar to pulleys 15, carried by suitable axles 14d, each extending into a cuff, as 13d, at each end. Each cuil` 13d is provided with a lug, as 21d, and a shaft, as 16d, having its inner end bent, as at 17, engages each of said lugs by means of a longitudinal curved slot, as 22d, the outer ends of shafts 16d being secured l to the upper ends of arcshaped arms, as l2,

each of said arms slidably engaging a bracket, The lower end of each arm 12d is provided with a suitable pulley, as 23d, and a cable, as 24d, having one end attached tothe main frame, as at 25d, is passed about the same and about a second pulley, as 26d, carried by a bracket, as 27d, secured to its respective side of the auxiliary frame, said cable being thence passed to and has its end secured about a centrallyarranged longitudinal shaft, as 28d, the cables 24d being passed about said shaft 28d from opposite sides, so that rotation of said shaft in one direction will take up both cables and rotation thereof in the opposite direction will pay out both cables. The shafts 16d of course carry suitable pulleys, which are designed to be adjusted to the. desired angle by rotation of shaft 28d, such rotationimparting longitudinal movement to arms 12d, the slotted en- IOC gagement of shafts 16d with lugs 21d permitting such movement, as will clearly appear from the dotted position of the parts in Fig. 17. rlhe structure disclosed in Figs. 21, 22, and

23 is preciselylthe same as that lastl above mentioned, with the exception that cuffs, as 13, are` employed, which .are not provided with lugs, but are bent upwardly at their outer ends, and the shafts, as 16, corresponding to shafts 16d, are not slotted longitudinally and are beveled on their inner ends instead of being bent. The other parts are the same with slight alterations in the `form of the combination of a main and an .auxiliary frame, tilting' belt-'supports carried thereby, and 2Vmeans for moving one of said frames relative to the otherfor adjusting said supports.
